Another SA Labor MP retires from politics

Another South Australian Labor MP is preparing to leave state politics after the party's election loss to the coalition earlier this year.

John Rau, 59, a former attorney-general, has announced he will stand down, just days after former Labor leader Jay Weatherill flagged his retirement.

"I think the best thing from both my perspective and the Labor party would be to have some renewal and have an energetic, fresh person to contribute to its efforts between now and the election," Mr Rau told the Adelaide Advertiser on Monday.
